Abstract
The purpose of the article is to substantiate the method and circuit design option for constructing an ultra-wideband radio receiver of the measuring system, mathematical modeling of the main parameters of the receiving path. It is shown the block diagram and general characteristics of the receiver. Including the dynamic range of received signals 111 dB, operating frequency range from 1 to 18 GHz. The article discusses the components of the receiver, such as: an automatic power control unit with a dynamic range of 50 dB and a tuning step of 1 dB, a preselector with six bandwidths 1–2,5; 2,5–4; 4–6; 6–11; 11–15; 15–18 GHz and a frequency conversion unit with three conversion steps. The structure is substantiated and the parameters of each of the blocks are given. A frequency conversion scheme with a final intermediate frequency of 0.75 GHz and a bandwidth of 500 MHz is considered in detail. Modeling of the noise figure, the distribution of the signal level along the receiver path from the input signal level and the results of modeling the output signal of the IF receiver.
